Abstract: A method and apparatus is disclosed for restoring curvature to the human spine. The apparatus includes a table for supporting a body in a supine position. Mounted to the table are resilient lumbar and cervical supports. The supports are each shaped to correspond substantially to their named posterior concavity of the spine for applying a static force to the concavity. A force actuator having a piston is spaced above the table to apply a force anteriorly to the spine through the body, the piston extended against and withdrawn from the body as the body resists the force through muscular action. The force actuator is longitudinally movable relative to the body in response to muscular action of the body.
